How to recognize this tactic
Mate in two usually opens with a forcing move — a check, a capture or an unstoppable threat — that strips the king of squares or defenders, so the follow-up mate becomes unavoidable. Look for the first move that leaves the opponent only losing replies.
General method: before you move, list the forcing candidates — every check, every capture, every direct threat — and calculate those first. The solution to a tactic is almost always among them.
Position on the board
White: king h1, queen f6, rook g1 h4, bishop d3, pawn c2 g2 h2 e5.
Black: king h8, queen g5, rook g7 g8, bishop d5, pawn b5 a6 f7 h7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 29.
The position in numbers
Material is level — 26 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h1, the black king on h8.
It is Black to move on move 29, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 4. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for Black: c, e, g.
The Black king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
29... Bxg2+ 30. Rxg2 Qxg2#
Why it works
- Great move! bishop to g2 keeps the pressure (#1).
- Well found: queen to g2 (#).
- The line ends in a forced mate in 2.
- If instead Rxg2, then Qxg2# and it is mate.
Move by move
- 29… Bxg2+ — bishop to g2 (capture) with check
- 30. Rxg2 — rook to g2 (capture)
- Qxg2# — queen to g2 (capture) and it is checkmate
Types in this puzzle
Supported queen mate
The queen delivers mate face to face, protected by a friend.
The supported queen mate is the most common pattern of all: the queen lands next to the king and mates because a friendly piece or pawn protects her. The king is helpless — capturing is impossible, and the queen covers every neighboring square herself. Hunt for a protected square beside the enemy king: a knight, bishop or pawn eyeing it turns her invasion into mate. Verify one thing — that the square really is defended, or the king eats her.
Mate in 2
A forced checkmate in two moves.
Mate in two: your move, any reply, then the mating blow. Start with the most forcing first moves — checks and sacrifices that shrink the opponent's options to almost nothing. Against every single reply you must have a mate ready, so check them all without exception. The common failure is analyzing the pretty defense and forgetting the boring one.
Mate defense
Mate is threatened — parry it and stay on top.
Mate defense: your opponent is one move from mating you — but it is your turn, and that changes everything. Find the defense that kills the mating threat while keeping your advantage: often a check or a counter-threat that leaves no time for the mate. First name the exact square where the mate would land — otherwise you are defending blind. The mistake is playing a "defensive" move that does not actually remove the threat.
